IDE :: Checking An Input String?
May 15, 2009
I do math applications for the web. Often I have to check if a user input is correct. For example: the right answer is 3x+5. Is the user input that.I do this by checking character by character. I don't think that it is the best way, especially since the user may have written 5+3x, which is right, too, although it is preferred to write the other way around.I sometimes have to check more complicated expressions, like -3x^2+7x-15 or -2 sin (4x^2).Right now I'm doing an equation solving exercise. There I have to check what the user wants to do to the equation, like +2x or /(-5).

Working on a simple dog and pony show that needs to fake some password entry. I'm in Flash CS3 using AS2.0.
I have an Input Text field named "txt_pinnums" and its line type is set to Password. It has a variable of "pinpassword".
All I want to do when "btn_ok" is pressed is check that the numbers entered on the keypad that are now in the input text field equal "1234". It seems though that the value of that field is a bunch of HTML, not simple characters. Here is what I have:
PHP Code:
stop();txt_pinnums.text = "";function checkPin() { if(pinpassword eq "1234") { trace("good"); } else { trace("bad"); }}btn_ok.onRelease = function() { checkPin();}
I'm sure my AS is not that good, but as I said this is just a simple show and tell demo that will be thrown away. How can I test that the input text equals 1234? If I do a trace(pinpassword) I get a bunch of HTML in addition to the characters entered.
Also, one syntactical question. I tried this:
PHP Code:
btn_ok.onRelease = checkPin;
But that doesn't work... that type of thing works in JS though. Curious as to why it doesn't work.

Is there a way to check if a string value loaded from a php script is actually a number?
Code: Doesn't work even when the value of evt.data is an integer, because AS thinks it's a string:
var returnValue:* = evt.data;
if(returnValue is int)
trace('true');[code]...

I'm working on a game that involves some timed animations and I need to fire a kind of 'failed' event.Basically I'm moving a clip from one point to another on the stage, the user has to input a correct key combination before the endpoint. I'm capturing the inputs correctly, but I need a default procedure to fire if the player doesn't input anything at all.So I'm guessing that at the endpoint I could check if my function to capture the key inputs was actually called, and if not, call the 'failed' procedure, or if at the endpoint, no keys were pressed, do the same

I have four text input boxes, and I need to be able to script it so that when the "Done" button is pushed each of the boxes are checked for the right input. I've tried two different methods, neither of which work or the answer is automatically correct.

I'm developing a diet checker that users enter their recipe into an input field and compares it to an external text file with a list variables of ingredients and then underlines or highlights certain ingredients that would not be good to eat.
I need to check this input box for certain words and see if there are specific words before or after those words.The word "egg" WOULD BE highlighted/underlined as a bad ingredient but "egg white" would NOT have the "egg" part highlighted The word "fried chicken" WOULD BE highlighted/underlined but "baked chicken" or "broiled chicken" would NOT be highlighted The external variable text file lists the words I'm searching for and the words to replace them with but, the code I have cannot yet determine if the word "white" is after the word "egg" and then not have the "egg" part of the phrase underlined.

ActionScript Code:
input.text = "[URL]";
function PlayVideo(event:MouseEvent):void {
switch (event.type) {
case "click":
var findVideo:RegExp = /(?<=?v=)([a-zA-Z0-9_-])+/;
trace(findVideo.exec(input.text));
break;
}}
I don't know what video this is (just picked it randomly off of the front page), but by clicking a button, the RegExp is called, looks for an ID in the input.text String, but when it does and I trace it, it gives me this:
ActionScript Code:
QGsGJlCpor4,4
What's with the ,4? How do I get rid of that?

I've been trying to compare two strings. One from an input text field, input_txt, and the other a variable. For some reason, even though both trace out exactly the same, it's not seeing a match.

I basically need to store a string of characters from an input text box and have them displayed at the last frame of the quiz. I declared the variable holding the input text as _global.player in the first frame, and upon clicking the start button the code is:
on (release) { _global.player=player.text; gotoAndStop (2); }
These variables are not referenced again until the last frame of the quiz, which reads thus:
stop();playerdisplay.text=_global.player;score.text=_global.correct;'Endng Comments Generator'if (_global.correct<=3) { phrase="Try a little harder next time";}if (_global.correct>3 + _global.correct<7) { }comment.text=phrase;
Yes, I know the global.correct coments are not yet complete, but i dont think that should be causing any issue with the playerdisplay.text (the dynamic text box to display the player name). If anyone could give me a hand that would be great. Nothing appears in the dynamic text box when the final frame of the movie loads.

I have an application that is trying to sort of scores. The problem is that when it tries to sort it errors as it is checking if one string is less than another string when it should be doing one number less than another number.
I have played with parseInt but I haven't managed to get it to work?
Code:
this.onEnterFrame = function() {
if (parseInt(yourtime_txt.text)<parseInt(pos1time_txt.text)) {
pos1time_txt.text = parseInt(yourtime_txt.text);

how to make a simple AS3 class.I've made a simple calculator application that allows you to add, subtract, multiply, and divide after entering 2 values into their respective text box.The problem, how ever, is once I moved it into it's own class, I cannot figure out how to reference the text fields. I have the movie clips referenced just fine, but, I cannot figure out the text fields.Here are the errors it's spitting out:
Code:
1120: Access of undefined property Number1_txt.
1120: Access of undefined property Number2_txt.
1120: Access of undefined property finalValue_txt.
And it does that for each instance of those in the Calculator.as
Main.as

package {
